Basement Mold Removal and Prevention

How to Detect, Remove, and Prevent Basement Mold

By Mark J. Donovan




If your basement is damp or occasionally floods, chances are you have basement mold growing in it. Basement mold can damage your home and become a health issue for your family.

Finding Basement Mold

To determine if you have basement mold growing in your basement there are number of things you can do. First, simply smell the basement. If it smells moldy, then you more than likely have basement mold growing. It is then just a matter of finding out where it is and getting rid of it. Finding basement mold is not always so easy.

Conventional building material is ideal for growing basement mold. Basement mold grows easily on wood and paper products, e.g. framing, faced insulation, and drywall.

To find out where the basement mold is growing, pay close attention to the ground level. Check the lower portion of the walls, particularly walls with drywall on them. Basement mold typically grows in dark, cool, moist places, so check behind paneling and drywall, and in basement closets. Also, lift carpets and look under them. Carpet is a great breeding ground for growing basement mold. If you have a dropped ceiling, lift some the ceiling tiles and check for mold growing on the backside of them.



Pay close attention to ceiling tiles that are directly under plumbing pipes. Also check around plumbing pipes and air conditioning duct work.

Removing Basement Mold

Once you have discovered the location of the basement mold, it is important to get rid of it. Use water with bleach to remove it. However when removing basement mold, make sure the basement is well ventilated and wear gloves and a facemask. Breathing in basement mold is unhealthy.

Basement Mold Prevention

The best way to prevent basement mold is to make sure the basement stays dry and that there is sufficient airflow in it.

If your basement is frequently damp or wet, then address the problem from the outside. Check that rain water drains away from the home, and if necessary install a perimeter drain around the home’s foundation.

In the event there is a leak in the basement it is important to clean it up quickly and thoroughly dry the area out.

Use a dehumidifier for most of the year in the basement, particularly during hot, humid summer days. These types of days are ideal for creating condensation on the plumbing pipes and A/C duct work. If the condensation drips onto wood or paper products basement mold will grow. To prevent condensation, insulate cold plumbing pipes and air condition duct work.

Make sure clothes dryers and basement bathrooms are vented to the outside.

Finally, use fans to circulate air in the basement. Basement mold typically likes to grow in cool, moist, stagnant air.
